So, as of today, I've only gotten hatchery chicks, nothing from a breeder and I plan on an out-crossing to a dorking to correct size and shape. At least with what I've seen so far, I just don't see progress in size any other way without spending 100 years selective breeding for size, and I don't have that kind of time, LOL.. These birds are seriously under sized!. And often, their legs are too long. I've made a plan, and I hope it works![]()
Now, if anyone is willing to talk about their experiences out-crossing to improve a breed, I'd love to hear about your experience? I know it's almost a taboo subject to some people?
Hmmm....an outcross may be the only realistic way to bring them back, but it wouldn't be easy. It would take an outstandingly firm capacity and willingness to cull--hard and in volume. There are some seriously divergent genetics going on here.
Before you go here go any further. This isn't for the faint hearted "I like to cuddle my chicks" person....
- Get the best Crevecoeurs cockerels possible. I don't think any are any good right now. The fact that one strain might be slightly better than another is of little importance. It's all the barrel of the bucket. Creves are among the rarest of all poultry. To that end, you need a partner or two or three, because your set up won't give you the space you need alone. Get the largest possible order of cockerels from MMCM. Raise them up, at eight to 12 weeks weigh them and check their earlobes. Keep the best; then cull the rest maybe even have another order coming.
- I'd get three to four White Dorking pullets that are a bit long in the leg. White Dorkings are black underneath, which is what you want, and it's easier to pull a V-comb through a rose comb than a single comb. Your Dorkings must have red earlobes because white in the earlobes is too prevalent in Crevecoeurs right now. If your Dorkings have white earlobes, the whole project will be for naught. Breed your three or four best cockerels to your three or four Dorking pullets.
- The first year you'd need to hatch every one to two weeks for four to six months, depending on how the black comes through. Hopefully you can cull for this at the incubator door. Hopefully in each hatch you'll have a portion of solid blacks.
- The fifth toe (Po) is dominant so chances are all of your chicks would have 5 toes, but they'd be split for 4 toes (po+); so, you won't fix the toe issue until the second generation. Muffs and beards are dominant; so most of the first generation will have some sort of muff, but they will vary in quality, you want the best you can get. Chances are you won't get any with a full crest, but most will have a Spitzhauben like tuft. Cull for earlobes. So, your first generation finalists will be black, with 5 toes, a muff, and a tuft with red earlobes.
- Second year. Do one or two breeding patterns. In the first, breed your biggest, most vigorous F1 pullets, with bright red earlobes back to your Crevecoeur cocks. You'd do this a lot. In each hatch you should get a portion of black chicks with beard, muff, four toes, and an obvious crest. It might be 20 to 30% of the hatch. Cull everything else. Be careful to toe-punch everything so you know who comes from whom and so that you can plan future pairings. Raise as many of these as possible. This would be your surest pairing. You'd need to raise as many of these as you can. This is where having a partner(s) is cool. After you've hit quota, you can pair F1 crosses with F1 crosses. You might get 2 to say 5 % that look about right. You'd keep like 3, 4, or 5 out of 100, but the chances that they'd be big breasted, big shouldered, blocky birds is pretty good. Should now be able to have three or four pairs of your own birds and step away from the original Creve cockerels. If not you have to go back again to them.
- Third year, just pair 'em and cull 'em. At the incubator door inspect toes, crest, muff. As they grow out, watch the earlobes (!!).
- Fourth year = same as third year, but things should be easier, and eventually you'll hit a new normal.
This is not an easy project. To be successful, in the first four years I wouldn't think anything less than hatching say 700-800 chicks, probably 1000-1200. You'd have to cull a lot at the incubator door: first year over 80%, second year 50-ish %, 3 year 25- 30%, fourth year and onwards under 20 % (all of this if you're lucky). This isn't easy to do. There are some breeds that have been given the "black dot" and Crevecoeurs are one of them. I doubt there are 20 good birds in the country, and I bet there are less than 5, if any at all, that could be called SQ. I don't write this for the sake of drama or intimidation; it's just the Crevecoeur reality. I'd love to see a line of Crevecoeurs in 10 years, but trying to do Creves is like trying to do Redcaps. They actually have to be rebuilt.
This is why Bob points to thinking twice before taking on the very rare. It's like your poultry project for a decade.
Plan B might be to get as many from DU as possible, and just go from there, but this might take a long, long time to select up, if at all, and even then you'd need partners so that when your blood runs dry you don't slip and slide backwards.
